To all whom it may concern.

Be it known that I, OTTO zen of the German Republic, residing at Breslau, Germany, have invented certain new and useful Improvements in .Circulat ing Devices (for which I have filed application in Germany Aug. 3, 1916, Patent No. 30$,d59), of which the following is aspecification. v I

This invention relates to improvements in water circulating devices as described in my U. S. A. Patent No. 829970 of itho-f Sep-. tember 1906 and it consists in arranging in the steam chamber of water circulating devices of this type, besides the outlet-nozzles which serve for the production ofthe water circulation and which are situated under the water level, other outlet-nozzles for the steam terminating upon the surface of the water and designed Ito produce a surface current in the water designed to remove the oil containin sediments which float :upon the surface ot the water. Part of the steam which collects in the steam chamber of the water circulating device is thus utilized for the production of the water circulation in the known manner, another part of this steam beingou'tilized for the production of the surface current.

In the accompanying drawings the invention is shown in combination with a water circulator.

Figs. 1 to 3 show the first form of construction in longitudinal section, in cross section and in plan view respectively.

Fig. 4: representsia constructional detail.

Fig. 5 is a longitudinal section of the second form of construction.

Fig. 6 is a. longitudinal section of the third form of construction.

In all the forms of execution which are shown, 7* designates the boiler flue tube, 8 the steam catching hood of the water circulator, h the steam collector proper, w the baffling plates, (1- and a the exhaust connecting branches of the steam collector, a the water level.

According to the invention the steam jet producer 0 is connected with the water circulator 7i, which is constructed in the well known manner. The device for removing the floating sediments consists of a steam tube 9 upwardly directed and of a trough d without front wall which is turned upside KUNERT, a 'citidifferent directions.

down and arranged at the height of the water level. This trough d is fan-shaped 'in plan View. The sidewalls of the trough are designated by a, lateral partitionse of the trough serve to divide the steam which is admitted to the trough into steam jets of As shown in Fig 1 the steam tube 1" is rigidly connected with the steam collecting hood h and mounted in thefront wall of the same between the exhaust connecting branches (6 and a, (Fig. 3) so that it com- .-1nun1cates with the steam. outlet opening Z).

As's'hown in Fig. 5. the positionof the regard to the height of the water level in the boiler. l/Viththis object in view the trough is made floatable owing to hollow spaces or it is provided with a counterweight glfloating upon the water so that the water pressure and the steam pressure maintain the trough d continually at the proper height. The up and down movement of said trough is very favorable for the result to be attained. 4

In all forms of construction the effect aimed at is attained through steam jets flowing out from the trough d in various direc-' tions, the steambeing conducted into said trough by means of the tube 1". The steam jets flow out of the trough horizontally so that they pass over the surface of the water and remove the layer of greasy sediments.

I claim z.-

1. In a steam-boiler the combination with a flue of a balfle forming a chamber partially surrounding said flue, a cap forming a steam chamber in communication with said chamber formed by the battle and dinozzles being situated upon the surface of the water. I

2. In a steam-boiler the combination with a flue of a battle forming a chamber partially surrounding said flue, a cap in communication with said chamber and divided into a number of compartments and outle -nozzles in communication with said cap and adapted to discharge in the longitudinal direction of the boiler, aid nozzles being partly open below and having an up wardly-incl ncd direction, some of said outlet-nozzles being situated below the surface of the water and some of said outlet-nozzles being situated upon the surface of the water.

3. in a steam-boiler the combination with a flue of a battle forming a chamber partially surrounding said flue, a cap in communication with said chamber and divided into a number of compartments and outlet-nozzles in communication with said cap and adaptor to disrharge in the longitutinal direction of the boiler said nozzles being partly open below andhaving an upward y-inc'lined and laterally-diverging direction, some of said outlet-nozzles being situated below the surface of the water and some of said outlet-nozzles being situated upon the surface of the water.

t. In a steam-boiler the combination with a fine of a battle forming a chamber partially surrounding said flue, a cap in communication with said chamber and divided into anumber of compartments and outlet-nozzles in conm'iunication with said cap and adapted to discharge in the longitudinal direction of the boiler said nozzles being partly open below and having an upwardly-inclined and laterally-diverging (,iireetion, and being provided with step-like upper surfaces, some of said outlet-nozzles being situated below the surface of the water and some of the outlet-nozzles being situated upon the surface of the water.

5. In a steam-boiler the combination with a flue of abafiie forming a chamber partially inclosing said fiue and having closed ends, a cap in communication with said chamber at its lower part, transverse clownwardly-extending partitions in said cap, out-letnozzles in communication with said cap and adapted to discharge in the longitudinal direction of the boiler and downwardly-extending partitions in said nozzles, the latter being partly open below, having an upwardly-inclined and laterally-diverging direction and being provided with steplike upper surfaces, some of said outletnozzles being situated below the surface of the water and some of said outlet-nozzles being situated upon the surface of the water.

In testimony whereof I affix my signature in presence of two witnesses.
